Original chain tensioner diaphragm pictures? - The Unofficial BMW M5 Messageboard (m5board.com)

Have anyone picture of an original chain tensioner when installed? The reason I´m asking this is that can S50B32 chain tensioner be recognized without removing it from engine? I think in my car is one of S50B32 version installed, because there isn´t that "diaphragm thing". I can´t see it, but I can feel it

...only that 32 mm cylinder/piston piece. Some pictures from an original one when installed would clear this thing. I have only seen pictures from that better one and disassembled pictures of the original.

Best Regards, Janne.

Thanks bay from a good and clear picture. So I have then an S50B32 item. Don´t have to buy one and take the current part away from engine only to see it is similar. The previous owner in Germany has done this good update

. I think it would be good to check that it´s installed with 70 nm torque and not with the original tensioners 55 nm, because there is some oil leak from the tensioner.
